摘要: This invention relates to the coating of textile sheets with polyurethane pastes by the reversal process for producing very soft coating articles with a hand resembling that of napa leather. The particular properties of the coating are obtained by using bonding pastes which contain a mixture which can be cross-linked by the action of heat, consisting of polyurethane hydrazodicarbonamides and melamine-formaldehyde resins and/or urea-formaldehyde resins.
